Grain Pattern
Straight grain with a very coarse, porous texture; distinct growth rings similar to Ash but more lightweight in appearance

Light blonde to pale grayish brown heartwood; sapwood is not clearly demarcated from heartwood. It maintains a silvery-grey luster and does not darken significantly with age.
Hardness (Janka)
300 lbf (Very Soft)
Durability & Decay Resistance
Durable to Very Durable; surprisingly resistant to rot and decay for its weight, though susceptible to insect attack if untreated
Value & Sustainability
- Estimated Market Value
- $6.00 - $10.00 per board foot
- Wood Age Estimate
- Recently milled modern lumber, likely from a fast-growing plantation tree under 15 years old
- Sustainability Status
- Not CITES listed; considered an invasive species in parts of North America but widely available via sustainable plantation growth
Common Uses
Musical instruments (especially electric guitar bodies and traditional Asian instruments), surfboards, boat building, carving, chests, and lightweight furniture
Geographic Origin
Native to Eastern Asia (China); extensively cultivated and naturalized in North America and Europe
Workability
Excellent workability due to low density; easily planed and sanded, though it can be so soft that it crushes under dull tools. Glues and finishes well.
Finish Recommendations
Water-based polyurethanes or light oils to preserve the pale color. Requires a sanding sealer due to its high porosity.
Notable Features
Exceptionally high strength-to-weight ratio; often called the 'aluminum of woods.' It is very dimensionally stable and has low thermal conductivity.
